I am an Assistant Professor in the Department of Computer Science at Hanyang University. I am jointly appointed with the Department of Artificial Intelligence. Before joining here, I was a postdoctoral research associate at Georgia Institute of Technology working with Prof. Polo’s data science group. I obtained my B.S. and Ph.D. degrees in Hanyang University under the supervision of Prof. Sang-Wook Kim. My research interests are broadly in the area of data mining, machine learning and AI. In the recent several years, my research interest was mainly focused on recommender systems. Currently I am interested in developing explainable & interpretable AI systems.
